The remote Ubuntu host is missing one or more security-related patches.

Description :

Yukihiro Matsumoto reported that Ruby's HTTP module uses blocking
sockets. By sending large amounts of data to a server application that
uses this module, a remote attacker could exploit this to render this
application unusable and not respond any more to other clients (Denial
of Service).
